I'm converting a powerpoint 2007 presentation into swf using ISpring. There is audio narration, and 2 wmv videos. The audio levels for the video files are lower than the narration. After conversion, it seems like the difference is greater, so audio can hardly be heard on the videos. Is there a way to boost the audio levels on the videos either by changing the compression rate, or something prior to conversion?

You would rather do it outside the product by using third party software like Audacity for editing audio or VirtualDub for editing video. After adjusting sound levels reattach media files to your presentation and repeat conversion.
